Abstract

The invention provides a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises an array substrate and a color film substrate. The array substrate comprises a data line, a scanning line, a thin film transistor and an open region. The array substrate further comprises a patterned flat layer formed on the data line, the scanning line and the thin film transistor and exposed out of the open region. A columnar protrusion is formed at the portion, located on the scanning line, of the patterned flat layer, the columnar protrusion is supported between the array substrate and the color film substrate, no spacer needs to be additionally manufactured, and therefore the procedure of manufacturing photosensitive spacers on the color film substrate is omitted.

Description

【Technical field】 [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display panel and a method for manufacturing the liquid crystal display panel. 【Background technique】 [0002] A traditional liquid crystal display panel includes a color filter (CF, Color filter) substrate, an array substrate and a liquid crystal. The color filter substrate includes a first glass substrate, a black matrix (BM, Black Matrix) layer, a colored pattern layer and a protective layer (OC, Over Coat) layer, the first glass substrate, a black matrix layer, a colored pattern layer and a protective layer The array substrate is sequentially stacked and arranged as a whole; the array substrate includes a second glass substrate, a gate line layer, an insulating layer, a semiconductor layer, a metal layer and a passivation layer, and the second glass substrate, a gate line layer, an insulating layer, a semiconductor layer, a metal layer The passivation...
